Hi Don.
I am not sure what you mean Don. If you read my last post i explained that i learned airway control as did all the PADI instructors and countless other number of divers from other forums. My point was that (according to the new PADI manual all the instructors i know and around 40 or 50 divers on other forums) you shouldnt be breathing with your tongue partially blocking the mouthpiece unless you had water in your regulator. The point of putting your tongue there is for it to act as a "splash guard" so you dont swallow water. There is no mention of breathing with your tongue partially blocking the mouthpiece when your regulator is functioning normally. If you were to breath like this all the time while underwater then you would almost surely increase the concentration of CO2 in your system. Maybe i missed something or i am going down the wrong road Don, either way lemme know because i am keen to learn. Perhaps some of the instructors need a refresher course, i doubt that , most of them teach diving in the Royal Navy. Don I arnt sure that any sort of airway control would have solved your problem in the situation you described. Can we have some more feedback from other divers please, i am keen to learn more, since that is why this thread was started, right?
PS: Don from your replies after my last post you seem a little upset, did i offend you in any way? or you for that matter Greg? Greg are you suggesting that "I" think Dons unfortunate incident was his own fault. I just think that such sneaky sarcastic comments lowers the tone and makes for an awkward atmosphere for other people wanting to add to the conversation.
nor will I, for that matter, but he certainly meant no disparagement. These are divers, they need to be taken with a grain of salt (pun intended
